Which method can extend the shelf life of baked goods?

Using preservatives is a well-known method for extending the shelf life of baked goods. Preservatives work by inhibiting the growth of molds, yeasts, and bacteria, which are factors that contribute to spoilage. Common preservatives found in baked goods include calcium propionate and potassium sorbate, which not only help in prolonging freshness but also maintain the quality of the product over time.

When baked goods contain preservatives, they can remain safe to consume and maintain their texture and flavor longer than those without. This is particularly important for products like bread, pastries, and cakes, which are more susceptible to mold and staleness.

In contrast, while ingredients like sugar can help retain moisture and improve flavor, they do not have the same effectiveness as preservatives in preventing spoilage. Storing baked goods in paper bags typically does not provide an airtight seal, which can lead to staleness rather than preservation. Lastly, keeping baked goods at room temperature can sometimes lead to faster spoilage, particularly in humid or warm environments, since it allows for greater exposure to air and potential contaminants.
